Kylo Ren

Vigilance

Whenever Kylo Ren attacks alone, you may sacrifice a nontoken Creature. If you do, put two +1/+1 counters on Kylo Ren and Kylo Ren gains double strike until end of turn.

LET THE PAST DIE - {u}{u}, {t}: Look at target opponents hand, then, that opponent discards a card at random. Do this only once on each of your turns.
